In some demonstrative embodiments, at least part of the functionality of controller 154 and/or message processor 158 may be implemented by an integrated circuit, for example, a chip, e.g., a System on Chip (SoC). In one example, the chip or SoC may be configured to perform one or more functionalities of radio 144. For example, the chip or SoC may include one or more elements of controller 154, one or more elements of message processor 158, and/or one or more elements of radio 144. In one example, controller 154, message processor 158, and radio 144 may be implemented as part of the chip or SoC.

In other embodiments, controller 154, message processor 158 and/or radio 144 may be implemented by one or more additional or alternative elements of device 140.

In some demonstrative embodiments, devices 102 and/or 140 may be configured to communicate according to a peer-to-peer protocol, e.g., in accordance with a WiFi Direct Services Specification and/or any other specification, which may provide a Peer-to-Peer connectivity, for example, to allow users to connect their devices in an easy and/or convenient manner, e.g., to share, show, print, and/or synchronize content.

In some demonstrative embodiments, devices 102 and/or 140 may be configured to provide one or more services to one or more remote devices. For example, device 102 may be configured to provide printing services, display services, Internet access services and/or any other services to device 140.

In some demonstrative embodiments, devices 102 and/or 140 may be configured to advertize the one or more services, for example, to enable the remote devices to find the services. For example, device 102 may be configured to advertise one or more of the services provided by device 102 to enable device 140 to discover the services provided by device 102.

In some demonstrative embodiments, devices 102 and/or 140 may be configured to utilize the one or more services from the remote devices. For example, device 140 may be configured to utilize the services from device 102.

In some demonstrative embodiments, devices 102 and/or 140 may be configured to connect to a device to receive the service provided by the device. For example, device 140 may be configured to connect to device 102 to receive the services provided by device 102.

In some demonstrative embodiments, devices 102 and 140 may establish a P2P connection between devices 102 and 140 over wireless communication medium 103 to connect between devices 102 and 140, and to provide the one or more services between devices 102 and 140.

In some demonstrative embodiments, devices 102 and 140 may establish any other additional or alternative connection between devices 102 and 140 over wireless communication medium 103.

In some demonstrative embodiments, devices 102 and/or 140 may include an Application Service Platform (ASP) configured to manage the procedure of receiving and/or providing the one or more services, e.g., according to a predefined protocol.

In some demonstrative embodiments, device 102 may include an ASP 164, and/or device 140 may include an ASP 174, configured to manage an ASP-session between devices 102 and 140.

In some demonstrative embodiments, controller 124 may be configured to perform one or more operations and/or functionalities of ASP 164 and/or to cause a wireless station implemented by device 102 to perform one or more operations and/or functionalities of ASP 164.

In some demonstrative embodiments, controller 154 may be configured to perform one or more operations and/or functionalities of ASP 174 and/or to cause a wireless station implemented by device 140 to perform one or more operations and/or functionalities of ASP 174.

In some demonstrative embodiments, ASP 164 and/or ASP 174 may include, for example, a software module and/or a library module that implements functions required for managing the procedure of receiving and/or providing the one or more services. For example, the functions may include discovery of a service, session management, connection topology management, security management and/or any other function to support management of the services.

In some demonstrative embodiments, ASP 164 and/or ASP 174 may be configured to establish one or more ASP sessions between devices 102 and 140 over the P2P connection. An ASP session may be utilized, for example, to provide the one or more services between devices 102 and 140.

In some demonstrative embodiments, an ASP session between devices 102 and 140 may include a logical link between ASP 144 and ASP 174, e.g., over a P2P connection between devices 102 and 140. The ASP session may be configured, for example, to allow to manage the procedure of providing a service between devices 102 and 140.

In some demonstrative embodiments, the ASP session may be identified by an identifier (“ASP-session identifier”), e.g., as described below.

In some demonstrative embodiments, the ASP-session identifier may be unique, e.g., different, for every ASP session. For example, a first ASP session may be identified by a first ASP-session identifier, and a second ASP session may be identified by a second, ASP-session identifier e.g., different from the first ASP-session identifier.

In some demonstrative embodiments, the ASP-session identifier may include a combination of one or more elements to identify, e.g., uniquely identify, the ASP session.

In some demonstrative embodiments, the ASP-session identifier may include a combination of a session media access control (MAC) address and a session identifier.

In some demonstrative embodiments, the session MAC address may include, for example, a MAC address of a device initiating the ASP session (also referred to as “the seeker device”).

In some demonstrative embodiments, the session identifier may include, for example, a value generated by the seeker device.

In some demonstrative embodiments, the seeker device may generate a different, e.g., unique, value for the session identifier, for example, for every ASP session initiated by the seeker device. Accordingly, the combination of the unique value for the session identifier and the session MAC address may uniquely form the ASP-session identifier for every ASP session.

In one example, ASP 164 and ASP 174 may establish a first ASP session over a P2P connection to provide a first service between devices 102 and/or 140, e.g., a printing service; a second ASP session over the P2P connection to provide a second, e.g., different, service between devices 102 and/or 140, e.g., a display service; and/or one or more other additional or alternative ASP sessions over the P2P connection to provide one or more other additional or alternative services between devices 102 and/or 140. According to this example, each ASP session may be identified by a combination of different unique session identifier generated by device 140 and the MAC address of device 140, for example, if device 140 initiates the ASP sessions.

In other embodiments, the ASP-session identifier may include any other identifier and/or may be based on one or more other additional or alternative values.

In some demonstrative embodiments, device 102 may include at least one service 168, e.g., a printing service and/or any other service, to be provided to another device, e.g., device 140.

In some demonstrative embodiments, service 168 may include a logical entity, which may utilize ASP 164 and/or 174 to provide use case functionalities to other services or applications. A service on one device may communicate with a service on one or more other devices using a common protocol defined in each service and the ASP. For example, service 168 may utilize ASP 164 and/or ASP 174 to provide printing functionalities to at least one service 178, e.g., implemented by at least one application.

In some demonstrative embodiments, device 140 may include at least one service 178, e.g., a browser and/or any other application, configured to use a remote service, e.g., service 168.

In some demonstrative embodiments, service 178 may include a software process having a user interface, which a user may employ to accomplish a task, e.g., web browsing, instant messaging, sending a file and/or streaming media. For example, a user of service 178 may utilize service 178 for the task of web browsing.

In some demonstrative embodiments, device 102 may advertise service 168 to enable another device, e.g., device 140, to discover service 168.

In some demonstrative embodiments, device 140 may receive the advertisement of service 168.

In some demonstrative embodiments, ASP 164 may communicate with ASP 174 via a P2P connection over WM 103 to manage an ASP session between ASP 164 and ASP 174.

In some demonstrative embodiments, ASP 164 and ASP 174 may manage the ASP session, for example, to enable and/or to manage usage of service 168 by device 140, for example, to enable the browser application to print content of a webpage.

Some procedures, for example, according to a Wi-Fi P2P (Wi-Fi Direct) Service Specification, may not be efficient and/or may have one or more disadvantages, for example, in some scenarios, implementations and/or use cases.

For example, a user experience may be degraded, for example, if a P2P device is required to wait for a predefined period, e.g., 2 minutes, to start a new discovery procedure, for example, when the P2P device is in a connection session setup procedure with a peer P2P device, and the peer P2P device becomes un available, suspends the connection session, encounters a wrong state, or is out of range, e.g., as described below.

FIG. 2 is a schematic illustration of communications and operations of a peer-to-peer session connection setup procedure between a first device 202, denoted Device A, and a station device 240, denoted Device B, which may be implemented in accordance with some demonstrative embodiments, for example, in compliance with a WiFi Direct Services Technical Specification.

In some demonstrative embodiments, as shown in FIG. 2, the device 202 may operate as a service advertiser to advertise a service 203 to be provided by an application 205 executed by device 202.

In some demonstrative embodiments, as shown in FIG. 2, the device 240 may operate as a service seeker to seek a service 203 to be provided to a service 243 of an application 247 executed by device 240.

In some demonstrative embodiments, devices 202 and 240 may be configured to perform one or more operations of a connection session setup procedure, e.g., to setup a P2P connection for an ASP session between devices 202 and 240.

In some demonstrative embodiments, as shown in FIG. 2, an ASP 249 of device 240 may send to an ASP 229 of device 202 a P2P provision discovery request 232.

In some demonstrative embodiments, as shown in FIG. 2, ASP 229 may set a timer (“waiting timer”) 234, for example, upon forwarding a session request to service 203, e.g., based on the P2P provision discovery request 232.

In some demonstrative embodiments, as shown in FIG. 2, ASP 229 may send a P2P provision discovery response 236 to ASP 249, for example, in response to the P2P provision discovery request 232.

In some demonstrative embodiments, as shown in FIG. 2, ASP 249 may set a waiting timer 236, for example, based on receipt of the P2P provision discovery response 238.

In some demonstrative embodiments, the waiting timer 234 and/or the waiting timer 238 may be set for a predefined waiting period, for example, 120 seconds, or any other waiting period.

In some demonstrative embodiments, ASP 229 may be allowed to reset the waiting timer, for example, upon receipt of a message (“ConfirmSession”) from service 203, e.g., to confirm the request to setup the session.

In some demonstrative embodiments, it may be inefficient and/or disadvantageous to require device 240 to remain in a waiting state after setting waiting timer 236, for example, until the timer expires or until a follow up P2P provision discovery request 240 is received from ASP 229.

In some demonstrative embodiments, it may be inefficient and/or disadvantageous to only allow device 240 to reset the waiting timer 236, for example, only upon receipt of the follow up P2P provision discovery request 240 is received from ASP 229.

For example, in some cases it may be inefficient and/or disadvantageous to require device 240 to remain in the waiting state until the waiting timer expires, for example, for the entire waiting period, e.g., 2 minutes, before allowing the device 240 start a new discovery process and/or free up a resource. For example, it may be inefficient and/or disadvantageous to require device 240 to remain in the waiting state until the waiting timer expires, for example, even in a case where Device A is walking away, suspends the connection session setup, or encounters a system error.

In some demonstrative embodiments, it may be inefficient and/or disadvantageous, e.g., at least in terms of user experience and/or power consumption, to have a P2P Device, e.g., device 240, wait for expiration of the waiting timer, e.g., to wait for the entire period of 2 minutes, before being allowed to get out of the waiting state, for example, in a case where the peer device, e.g., device 202 suspends or stops the connection session setup. The waiting time, e.g., 2 minutes, may be too long, and may, for example, cause bad user experience and/or one or more other inefficiencies and/or disadvantages.

Referring back to FIG. 1, in some demonstrative embodiments, devices 102 and/or 140 may be configured to utilize a signaling mechanism, which may be configured to allow a P2P device, e.g., device 140, which is in a “waiting” state with respect to a peer P2P device (also referred to as “remote P2P device”), e.g., device 102, to check a state of the remote P2P device, for example, to check whether the remote P2P device is still in range and still in a valid state of processing a connection request and response transaction, e.g., of the session connection setup procedure.

In some demonstrative embodiments, the P2P device, e.g., device 140, may be configured to check and/or determine a status of a remote P2P device, e.g., device 102, for example, to determine whether or not to continue waiting in a waiting state, for example, to determine to avoid “sticking” in the waiting state, e.g., as described below.

In some demonstrative embodiments, enabling the P2P device, e.g., device 140, to determine the sate of the remote P2P device, e.g., device 102, for example, when the P2P device is at the “waiting” state, may enable the P2P device to get out of the “waiting” state, for example, quickly, e.g., before expiration of the “waiting” timer, for example, if the remote P2P device is not any more in the connection request/response transaction.

In some demonstrative embodiments, devices 102 and/or 140 may be configured to use one or more messages, which may be configured to enable to check and/or confirm whether the remote P2P device is in the valid state, e.g., as described below.

In some demonstrative embodiments, devices 102 and/or 140 may be configured to use a Probe Request and/or a Probe Response, which may be configured to enable to check and/or confirm whether the remote P2P device is in the valid state, e.g., as described below.

In some demonstrative embodiments, devices 102 and/or 140 may be configured to communicate the Probe Request and/or the Probe Response, for example, during the connection session setup procedure, e.g., as described below.

In some demonstrative embodiments, the Probe Request frame may be configured to include an attribute, which may be, for example, included in a P2P Information Element (IE), e.g., as described below.

In some demonstrative embodiments, devices 102 and/or 140 may be configured to generate, process and/or communicate a probe request frame and/or a probe response frame including information to identify a session for which the status of the remote P2P device is to be checked and/or confirmed, e.g., as described below.

In some demonstrative embodiments, devices 102 and/or 140 may be configured to generate, process and/or communicate a probe request frame and/or a probe response frame including a Session Identifier (ID) information (Info) attribute (“Session ID Info attribute”), e.g., as described below.

In some demonstrative embodiments, a P2P device, e.g., device 140, which is in a “waiting” state with respect to a peer P2P device, e.g., device 102, may be configured to generate and transmit to the remote P2P device, e.g., device 102, a Probe Request frame with a P2P IE including the Session ID Info attribute, for example, to identify a session that the P2P device, e.g., device 140, would like to confirm, e.g., as described below.

In some demonstrative embodiments, the remote P2P device, e.g., device 102, may be configured to, upon receipt of the Probe Request frame with the Session ID Info attribute, transmit a Probe Response frame with the Session ID Info attribute, for example, if the remote P2P device is still performing the connection session setup transaction, e.g., if the state of the connection session procedure is valid. Otherwise, the remote P2P device, e.g., device 102, may select not to transmit a Probe Response, or may select to transmit a Probe Response without the Session ID Info attribute, for example, if the remote P2P device is not performing the connection session setup transaction.

In some demonstrative embodiments, enabling the P2P device, e.g., device 140, to request the remote P2P device, e.g., device 102, to indicate a connection session status of the remote P2P device, and/or enabling the remote P2P device to signal the connection session status of the remote P2P device, may allow the P2P device, which is “waiting” for the remote P2P device, to detect whether the remote P2P device is in the valid state or not.

In some demonstrative embodiments, the P2P device, e.g., device 140, may be allowed to quickly get out of the “waiting” state, for example, even before expiration of the timer, e.g., even without needing to wait for the waiting period, e.g., two minutes, and be allowed to start a new discovery, for example, if the remote P2P device, e.g., device 102, encounters a system error or moves away.

In some demonstrative embodiments, enabling the P2P device, e.g., device 140, to request the remote P2P device, e.g., device 102, to indicate a connection session status of the remote P2P device, and/or enabling the remote P2P device to signal the connection session status of the remote P2P device, may allow, for example, at least to improve user experience, an/or may provide a more power efficient discovery for P2P devices.

In some demonstrative embodiments, the Session ID info attribute may include one or more fields, which may be configured to identify a session, e.g., as follows:

TABLE 1 Field Size (octets) Value Description Attribute 1 26 Identifying the type of P2P ID attribute. The specific value is defined in Table 6 of a Wi-Fi P2P Technical Specification (P2P Attribute ID definitions) Length 2 10 Length of the following field in the attribute. Session ID 4 0x00000000- Value of the session_id 0xFFFFFFFF Session 6 Variable P2P device address of the P2P MAC device which assigned the Address session_id

In some demonstrative embodiments, the Session ID Info attribute may uniquely identify a session, e.g., an ASP session (ASP-Session). The Session ID Info attribute may be used, for example, in Provision Discovery Request frames to request ASP-Session establishment to a specific Wi-Fi Direct service on a peer device.

In some demonstrative embodiments, a device, for example, a P2P device, e.g., device 102 and/or device 140, may be configured to include the Session ID Info attribute in a Provision Discovery Request frame and/or in a Provision Discovery Response frame, e.g., in accordance with a Wi-Fi P2P Technical Specification, and/or any other Specification or Protocol.

In some demonstrative embodiments, a device, for example, a P2P device, e.g., device 102 and/or device 140, may be configured to include the Session ID Info attribute in a Probe Request frame, and/or a Probe Response frame, e.g., as described below.

In some demonstrative embodiments, a device, for example, a P2P device, e.g., device 102 and/or device 140, may be configured to generate, transmit, receive, access, and/or process a probe request frame and/or a probe response frame including the Session ID Info attribute, e.g., as described below.

In some demonstrative embodiments, devices 102 and/or 140 may be configured to include the Session ID Info attribute in a Probe Request frame, and/or a Probe Response frame, for example, if the session is matched.

In some demonstrative embodiments, two devices, e.g., devices 102 and/or 140, may be configured to include the Session ID Info attribute in the Probe Request and/or Probe Response frames, for example, to check whether the two devices are still in the process of the connection session setup, e.g., as described below.

In some demonstrative embodiments, the Session ID Info attribute may uniquely identify a session, e.g., an ASP-Session.

In some demonstrative embodiments, the Session ID Info attribute may be used in the Provision Discovery Request frames to request ASP-Session establishment to a specific Wi-Fi Direct service on a peer device.

In some demonstrative embodiments, a P2P device, e.g., device 102, may be allowed to respond to a Probe Request frame, for example, when the P2P device is in the connection setup for an ASP session with a remote ASP2 Device, e.g., device 140, that transmits the Probe Request frame, e.g., as described below.

In some demonstrative embodiments, the Session ID Info attribute of Table 1 may include a Session ID value, and a Session MAC address, which may uniquely identify a session. For example, a combination of the Session ID and the MAC address may uniquely identify the session, e.g., as described above.

In some demonstrative embodiments, the Session ID may be assigned, for example, by a Seeker device, e.g., which first transmits a Provision Discovery Request frame, e.g., including the Session ID Info attribute with the Session ID, e.g., as described above.

In some demonstrative embodiments, the Session MAC Address may include a MAC address of a P2P Device, e.g., in this case the Seeker device, which assigned the value of the Session-id, e.g., as described above.

In some demonstrative embodiments, for example, if two devices, e.g., devices 102 and 140, are in a connection session setup, both devices should have the same contents of Session ID Info. For example, the Session ID and Session MAC address for both devices may be identical (match).

In some demonstrative embodiments, a Probe Request frame format may be configured to include the Session ID Info attribute, e.g., of Table 1, for example, as a P2P attribute, e.g., as follows:

TABLE 2 Attributes Attribute ID Note Session ID 26 The Session ID Info attribute may be present Info in the P2P IE if ASP2-P2P is supported. The usage of this attribute is defined in the ASP2 technical Specification [x].

In some demonstrative embodiments, a Probe Response frame format may be configured to include the Session ID Info attribute, e.g., of Table 1, for example, as a P2P attribute, e.g., as follows:

TABLE 3 Attributes Attribute ID Note Session ID 26 The Session ID Info attribute may be present Info in the P2P IE if ASP2-P2P is supported. The usage of this attribute is defined in the ASP2 technical Specification [x]

In some demonstrative embodiments, when a device, for example, an ASP2 Device, e.g., either Service Advertiser or Service Seeker, for example, device 140, is in the waiting of a timer, e.g., a 120 second timer, the ASP2 Device may transmit a unicast Probe Request frame including the Session ID Info attribute to a remote ASP2 Device, e.g., device 102, for example, to check whether the remote ASP2 Device is still in the same connection session setup process.

In some demonstrative embodiments, a P2P device, e.g., device 102, shall be allowed to respond to a Probe Request frame, for example, in the connection setup for an ASP session with a remote ASP2 Device, e.g., device 140, that transmits the Probe Request frame.

In some demonstrative embodiments, upon receipt of the Probe Request frame with the Session ID Info attribute, the remote ASP2 Device, e.g., device 102, shall respond with a Probe Response frame including the Session ID Info attribute, e.g., if the remote ASP2 Device is in the same connection session setup.

In some demonstrative embodiments, for example, if the remote ASP2 Device is not in the same connection setup, the remote ASP2 Device shall transmit the Probe Response frame without the Session ID Info attribute.

In some demonstrative embodiments, if a device, for example, the ASP2 Device, e.g., device 140, that successfully transmitted the Probe Request frame including the Session ID Info attribute, receives the Probe Response frame without matched Session ID Info, the device may consider the connection session setup failed and may stop the waiting timer, e.g., the 120 second timer.

In some demonstrative embodiments, if the device, for example, the ASP2 Device, e.g., device 140, that successfully transmitted the Probe Request frame including the Session ID Info attribute, does not receive any Probe Response frame, the Device may consider the connection session setup failed and may stop the 120 second timer.

In some demonstrative embodiments, before concluding the connection session setup failed, the device, for example, the ASP2 device, that successfully transmitted the Probe Request frame, e.g., device 140, should consider retransmitting the Probe Request frame and repeat the procedure, for example, in case the remote device, e.g., device 102, may be temporarily unavailable.

In some demonstrative embodiments, an interval of the Probe Request frames that the ASP2 Device transmits should not be less than a predefined period, e.g., one second.

In some demonstrative embodiments, the 120 second timer may be due, for example, to either auto_accept set to FALSE or waiting for PIN input, or any other reason.

In some demonstrative embodiments, controller 154 may be configured to control, cause and/or trigger a peer-to-peer device implemented by device 140 to generate a probe request including a session ID Info attribute, e.g., including one or more of the fields of Table 1.

In some demonstrative embodiments, controller 154 may be configured to control, cause and/or trigger the peer-to-peer device implemented by device 140 to transmit the probe request to a second peer-to-peer device, e.g., device 102, for example, during a connection session setup of a session with the second peer-to-peer device.

In some demonstrative embodiments, the probe request may include a unicast frame individually addressed to the second peer-to-peer device.

In some demonstrative embodiments, the session may include an ASP session, e.g., an ASP2 session, between ASP 174 and ASP 164, e.g., as described above.

In some demonstrative embodiments, controller 124 may be configured to control, cause and/or trigger the peer-to-peer device implemented by device 102 to process the probe request received from device 140 during the connection session setup of the session, and to transmit to device 140 a probe response in response to the probe request.

In some demonstrative embodiments, the probe response may include the session ID Info attribute, e.g., including one or more of the fields of Table 1.

In some demonstrative embodiments, the Session ID Info attribute may include a Session ID field including a value of a session ID, and a session MAC address field including a peer-to-peer device address, e.g., as described above.

In some demonstrative embodiments, a combination of the session ID and the peer-to-peer device address may uniquely identify the session, e.g., as described above.

In some demonstrative embodiments, the session MAC address field may include, for example, a peer-to-peer device address of a peer-to-peer device, by which the session ID is assigned, for example, the MAC address of the service seeker, e.g., as described above.

In some demonstrative embodiments, controller 154 may be configured to control, cause and/or trigger the peer-to-peer device implemented by device 140 to set a waiting timer to count a waiting period during a connection session setup of a session with a second peer-to-peer device, e.g., the peer-to-peer device implemented by device 102.

In some demonstrative embodiments, the session may include an ASP session, e.g., an ASP2 session, between ASP 174 and ASP 164, e.g., as described above.

In some demonstrative embodiments, the waiting timer may include a 120 second timer, e.g., as described above, or any other timer.

In some demonstrative embodiments, controller 154 may be configured to control, cause and/or trigger the peer-to-peer device implemented by device 140 to check whether the second peer-to-peer device is in the connection session setup during the waiting period, for example, by transmitting to the second peer-to-peer device a probe request including an Info attribute.

In some demonstrative embodiments, the probe request may include a unicast frame individually addressed to the second peer-to-peer device, e.g., as described above.

In some demonstrative embodiments, the Info attribute may include a Session Identifier (ID) Info attribute, e.g., as described above.

In some demonstrative embodiments, the Session ID Info attribute may include a Session ID field including a value of a session ID, and a session MAC address field including a peer-to-peer device address, e.g., as described above.

In some demonstrative embodiments, controller 154 may be configured to control, cause and/or trigger the peer-to-peer device implemented by device 140 to determine a failure of the connection session setup and to stop the waiting timer during the waiting period, for example, if a probe response, which includes the Info attribute, e.g., the same Info attribute included in the probe request, is not received from the second peer-to-peer device, e.g., within a predefined time period from transmitting the probe request.

In some demonstrative embodiments, controller 154 may be configured to control, cause and/or trigger the peer-to-peer device implemented by device 140 to retransmit the probe request during the waiting period, for example, if a probe response, which includes the Info attribute, e.g., the same Info attribute included in the probe request, is not received from the second peer-to-peer device.

In some demonstrative embodiments, controller 154 may be configured to allow the peer-to-peer device implemented by device 140 to determine the failure of the connection session setup and stop the waiting timer during the waiting period, for example, if no probe response is received from the second peer-to-peer device.

In some demonstrative embodiments, controller 154 may be configured to allow the peer-to-peer device implemented by device 140 to determine the failure of the connection session setup and stop the waiting timer during the waiting period, for example, if a probe response, which does not include the Info attribute, e.g., a probe response which does not include the same Info attribute included in the probe request, is received from the second peer-to-peer device.

In some demonstrative embodiments, controller 124 may be configured to control, cause and/or trigger the peer-to-peer device implemented by device 102 to set a waiting timer to count a waiting period, e.g., the 120 second period, during the connection session setup of the session, e.g., the ASP session, with the peer-to-peer device implemented by device 140.

In some demonstrative embodiments, controller 124 may be configured to control, cause and/or trigger the peer-to-peer device implemented by device 102 to process the probe request including the Info attribute from device 140, for example, during the waiting period, e.g., as described above.

In some demonstrative embodiments, controller 124 may be configured to control, cause and/or trigger the peer-to-peer device implemented by device 102 to transmit to the peer-to-peer device implemented by device 140 a probe response, for example, upon receipt of the probe request including the Info attribute from device 102 during the waiting period.

In some demonstrative embodiments, controller 124 may be configured to control, cause and/or trigger the peer-to-peer device implemented by device 102 to transmit the probe response, which includes the Info attribute, e.g., the same Info attribute included in the probe request, for example, when the peer-to-peer device implemented by device 102 is still in the connection session setup.

In some demonstrative embodiments, controller 124 may be configured to control, cause and/or trigger the peer-to-peer device implemented by device 102 to transmit the probe response, which does not include the Info attribute, e.g., which does not include the same Info attribute included in the probe request, for example, when the peer-to-peer device implemented by device 102 is not in the connection session setup.

In some demonstrative embodiments, controller 124 may be configured to control, cause and/or trigger the peer-to-peer device implemented by device 102 to select not to transmit the probe response, e.g., in response to the probe request, for example, when the peer-to-peer device implemented by device 102 is not in the connection session setup.

Reference is made to FIG. 3, which schematically illustrates communications and operations of signaling a peer-to-peer connection state during connection session setup, e.g., according to a first signaling scheme, and to FIG. 4, which schematically illustrates communications and operations of signaling a peer-to-peer connection state during connection session setup, e.g., according to a second signaling scheme, in accordance with some demonstrative embodiments.

In some demonstrative embodiments, as shown in FIGS. 3 and 4, a first device 302, denoted Device A, and a station device 340, denoted Device B, may be configured, for example, to perform one or more operations and/or communications to signal a peer-to-peer connection state, e.g., as described below. For example, device 102 (FIG. 1) may be configured to perform one or more operations and/or functionalities of device 302, and/or device 140 (FIG. 1) may be configured to perform one or more operations and/or functionalities of device 340.

In some demonstrative embodiments, devices 302 and/or 340 may be configured to perform one or more operations and/or communications of FIGS. 3 and/or 4, for example, in a provision discovery scenario, for example, of a deferred failure detected by a remote device, e.g., as described below.

In some demonstrative embodiments, as shown in FIGS. 3 and 4, the device 302 may operate as a service advertiser to advertise a service 303 to be provided by an application 305 executed by device 302.

In some demonstrative embodiments, as shown in FIGS. 3 and 4, the device 340 may operate as a service seeker to seek a service 303 to be provided to a service 343 of an application 347 executed by device 340.

In some demonstrative embodiments, devices 302 and 340 may be configured to perform one or more operations of a connection session setup procedure, e.g., to setup a P2P connection for an ASP session between devices 302 and 340.

In some demonstrative embodiments, as shown in FIGS. 3 and 4, an ASP 349 of device 340 may send to an ASP 329 of device 302 a P2P provision discovery request 332. For example, ASP 164 (FIG. 1) may be configured to perform one or more operations and/or functionalities of ASP 329, and/or ASP 174 (FIG. 1) may be configured to perform one or more operations and/or functionalities of ASP 349.

In some demonstrative embodiments, P2P provision discovery request 332 may include, for example, a Session ID Info attribute may uniquely identify a session, e.g., an ASP session, to be established between ASP 329 and ASP 349, e.g., as described above.

In some demonstrative embodiments, the Session ID Info attribute may include, for example, a Session ID value, and a Session MAC address, e.g., as described above. For example, the Session ID Info attribute may include the fields of Table 1.

In some demonstrative embodiments, the Session ID may be assigned, for example, by Service Seeker 313, e.g., as described above.

In some demonstrative embodiments, the Session MAC Address may include a MAC address of device 340, which assigns the value of the Session-id, e.g., as described above.

In some demonstrative embodiments, as shown in FIGS. 3 and 4, ASP 329 may set a waiting timer 334, for example, upon forwarding a session request 335 to service 303, e.g., based on the P2P provision discovery request 332.

In some demonstrative embodiments, as shown in FIGS. 3 and 4, ASP 329 may send a P2P provision discovery response 336 to ASP 349, for example, in response to the P2P provision discovery request 332.

In some demonstrative embodiments, the P2P provision discovery response 336 may include, for example, the Session ID Info attribute, e.g., including the same fields of the Session ID Info attribute, which was included in the P2P provision discovery request 332.

In some demonstrative embodiments, as shown in FIGS. 3 and 4, ASP 349 may set a waiting timer 336, for example, based on receipt of the P2P provision discovery response 338, e.g., upon receiving P2P provision discovery response 338 including the same Session ID info attribute, which was included in the P2P provision discovery request 332.

In some demonstrative embodiments, ASP 329 may be configured to set the waiting timer 334 to a predefined waiting period, for example, 120 seconds, or any other waiting period; and/or ASP 349 may be configured to set the waiting timer 336 to a predefined waiting period, for example, 120 seconds, or any other waiting period.

In some demonstrative embodiments, as shown in FIGS. 3 and 4, devices 302 and/or 340 may be configured to perform one or more operations and/or communications, for example, when a service, e.g., service 303, sets auto accept to FALSE, and an ASP2 Device, e.g., device 340, detects failure on a remote ASP2 Device, e.g., device 302, for example, a system error or an out of range error, e.g., as described below. In other embodiments, one or more of the operations of FIGS. 3 and/or 4 may be implemented with respect to one or more additional or alternative scenarios, implementations, and/or use cases.

In some demonstrative embodiments, as shown in FIGS. 3 and 4, device 340 may be in a waiting state, for example, during the connection session setup procedure. For example, device 340 may operate at the waiting state to wait, for example, upon setting waiting timer 338, e.g., to wait to receive from ASP 329 a message of the connection session setup procedure.

In some demonstrative embodiments, as shown in FIGS. 3 and 4, device 340 may send a Probe Request 360, e.g., a unicast probe request individually addressed to device 302, for example, during the waiting period, e.g., before expiration of the waiting timer 338.

In some demonstrative embodiments, as shown in FIGS. 3 and 4, the probe request 360 may include a Session ID Info attribute.

In some demonstrative embodiments, the Session ID Info attribute may include the Session ID and Session MAC address, for example, to identify the connection session. For example, ASP 349 may send the probe request 360 including the same Session ID Info attribute, e.g., including the same Session ID and the same Session MAC address, which were included in the P2P provision discovery request 332.

In some demonstrative embodiments, as shown in FIGS. 3 and 4, device 302 may receive the probe request 360. For example, ASP 329 may process the probe request 360 from ASP 349.

In some demonstrative embodiments, as shown in FIG. 3, device 302 may send a Probe Response 463 to device 340, e.g., in response to the probe request 360.

In some demonstrative embodiments, as shown in FIG. 3, ASP 329 may send to ASP 349 the Probe Response 362 without including the Session ID Info attribute in the probe response 362, for example, if device 302 is not in the connection session transaction any more, e.g., not in the valid state 361.

In some demonstrative embodiments, as shown in FIG. 4, ASP 329 may select not to send a Probe Response to ASP 349, e.g., by selecting not to respond to probe request 360, for example, if device 302 is not in the connection session transaction any more, e.g., if device 302 is moving away, or if device 302 encounters some system error.

In some demonstrative embodiments, ASP 329 may send to ASP 349 a Probe Response with the Session ID Info attribute (not shown in FIG. 3 or 4), e.g., matched to the Session ID Info attribute in the Probe Request 360, for example, if device 302 is in the process of the connection request/response transaction, for example, if device 302 is at a valid state of the session connection procedure, e.g., as described above.

In some demonstrative embodiments, upon receipt of the Probe Response with the Session ID Info attribute (not shown in FIG. 3 or 4), e.g., matched to the Session ID Info attribute in the Probe Request 360, ASP 349 may continue to operate in the waiting state, e.g., while continuing to count the waiting timer 336.

In some demonstrative embodiments, as shown in FIGS. 3 and 4, ASP 349 should come out of the waiting time, for example, if device 340 receives no Probe Response frame (FIG. 4) or receives the Probe Response frame 362 without the matched Session ID Info attribute (FIG. 3).

In some demonstrative embodiments, as shown in FIGS. 3 and 4, ASP 349 should come out of the waiting time, for example, by resetting the waiting timer (369), and passing up a “connection failure” event 364, e.g., to service 343, to indicate a failure of setting up the ASP session.

In some demonstrative embodiments, enabling device 302 to signal to device 340 whether or not device 302 is still performing the session connection setup procedure, e.g., using the probe request/response messages, may enable device 340 reset the waiting timer (369) and provide the failure status 364, for example, even before expiration of the waiting timer.

In some demonstrative embodiments, a service seeker, e.g., device 340, may be configured to transmit a probe request during the waiting period of the connection session setup, and a service advertiser, e.g., device 302, may be configured to selectively transmit a probe response in response to the probe request, for example, to signal a status of the service advertiser, e.g., as described above.

In some demonstrative embodiments, the service advertiser, e.g., device 302, may transmit a probe request during the waiting period of the connection session setup, and the service seeker, e.g., device 340, may selectively transmit a probe response in response to the probe request, for example, to signal a status of the service seeker, e.g., as described below.

In some demonstrative embodiments, device 302 may be configured to transmit a probe request including the Session ID Info attribute, e.g., the same Session ID Info attribute included in the P2P Provision Discovery Request 332; and/or device 340 may be configured to selectively transmit a probe response including the Session ID Info attribute, e.g., in response to the probe request.

In some demonstrative embodiments, ASP 329 may be configured to allow device 302 to exit the waiting state earlier, for example, in the case of system error of device 340, e.g., based on a probe request with a Session ID Info attribute sent from device 302.

For example, ASP 329 may identify one or more failures, e.g., if:

-   -   device 302 sends a Probe Request with a Session ID Info         attribute and gets no answer from device 340;     -   device 302 sends a Probe Request with a Session ID Info         attribute and gets a response without a matching Session ID Info         attribute; and/or     -   device 302 receives Probe Response without a Session ID Info         attribute from device 340.

In some demonstrative embodiments, ASP 349 may be configured to identify an error of device 302, for example, if device 340 receives a Probe Request without a Session ID Info attribute from device 302.

In some demonstrative embodiments, a probe request and/or a probe response may be configured to include a Session ID Info attribute, for example, to identify a session of a connection session procedure, e.g., as described above.

In some demonstrative embodiments, the probe request and/or probe response may include any other information element, attribute, and/or field, which may be configured to identify a session of a connection session procedure, e.g., as described below.

In some demonstrative embodiments, the Probe Request frame and/or the probe response frame may be configured to include an attribute (the “Connection Session Status (CSS) attribute”), which may be, for example, included in a P2P Information Element (IE). For example, device 340 may send a Probe Request with a CSS attribute to device 302, for example, during a waiting period, e.g., before expiration of a waiting timer; and device 302 may receive the probe request, and may send to device 340 a Probe Response with the CSS attribute, for example, if the device 302 is in the process of the connection request/response transaction.

In some demonstrative embodiments, the CSS attribute may be included in a P2P IE, for example, in the form of a peer MAC address field, e.g., follows:

TABLE 4 Size Field (octets) Value Description Attribute ID 1 0x02 Identifies the type of P2P attribute. Length 2 Variable Length of the following fields in the attribute. Peer MAC 6 Variable Indicating the MAC address of the address remote P2P device address that is engaged in the connection session.

For example, a field of the Connection Session Status attribute, e.g., in a peer MAC address field of Table 4, may be set to include a remote P2P device MAC address which is in the middle of a connection session setup transaction.

Reference is made to FIG. 5, which schematically illustrates a method of signaling a peer-to-peer connection state during connection session setup, in accordance with some demonstrative embodiments. For example, one or more of the operations of the method of FIG. 5 may be performed by one or more elements of a system, e.g., system 100 (FIG. 1), for example, one or more wireless devices, e.g., device 102 (FIG. 1), device 140 (FIG. 1), device 302 (FIG. 3), and/or Device 304 (FIG. 4); a controller, e.g., controller 124 (FIG. 1) and/or controller 154 (FIG. 1); an ASP, e.g., ASP 164 (FIG. 1), ASP 174 (FIG. 1), Asp 329 (FIG. 3), and/or ASP 349 (FIG. 3); a radio, e.g., radio 114 (FIG. 1) and/or radio 144 (FIG. 1); a transmitter, e.g., transmitter 118 and/or transmitter 148 (FIG. 1); a receiver e.g., receiver 116, and/or receiver 146 (FIG. 1); and/or a message processor, e.g., message processor 128 (FIG. 1) and/or message processor 158 (FIG. 1).
